Abstract
A repeater including an hours piece mounted to rotate between a rest position and a reading position; a device for regulating the angular speed of the hours piece, which includes a rotor and a system for braking the rotor; and a transmission gear train between the hours piece and the rotor, this gear train including a disengageable primary mobile able to adopt two configurations: a) an engaged configuration in which the primary mobile couples the hours piece to the rotor while the hours piece is moved from its reading position to its rest position; b) a disengaged configuration in which the primary mobile decouples the rotor from the hours piece as soon as the latter is stopped in the rest position.
Claims16
A repeater mechanism for a timepiece with a striking mechanism, which comprises:
- an hours snail;
- an hours piece provided with a toothed sector and carrying an hours follower, the hours piece being mounted to rotate between a fixed rest position, wherein the hours follower is angularly spaced from the hours snail, and a reading position wherein the hours follower comes into contact with the hours snail;
- a device for regulating the angular speed of the hours piece, which comprises a rotor and a system for braking the rotor;
- a transmission gear train between the hours piece and the rotor;
- wherein the transmission gear train comprises a disengageable primary mobile able to adopt two configurations:
- a) an engaged configuration wherein the primary mobile couples the hours piece and the rotor while the hours piece is moved from its reading position to its rest position;
- b) a disengaged configuration wherein the primary mobile decouples the rotor and the hours piece as soon as the latter is stopped in the rest position.
